Using engine thrust for flight control, also known as Propulsion-Controlled Aircraft (PCA), is a possible emergency control method after total failure of normal flight control system. In response to the fact that the maneuverability of PCA in existing research is mainly evaluated through simulators and flight tests, this paper theoretically derives and establishes a prediction method for longitudinal and lateral maneuverability of PCA control. Based on parameters of typical civil transport aircraft, the differences in dynamic mechanisms between PCA control and conventional aerodynamic control surface are revealed, and typical boundaries of maneuverability are predicted. The results indicate that, for civil transport aircraft, the contribution terms of PCA manipulation to normal load factor include, in descending order, the angle of attack term, airspeed term, and the normal component term of thrust. The ability to generate roll rate is directly proportional to magnitude of differential thrust, roll static stability, and engine span arm, and inversely proportional to roll damping and yaw static stability. From a perspective of quantitative maneuverability, for a typical civil transport aircraft, the maximum normal load capacity of PCA manipulation is about 0.2g, with the contribution ratio of angle of attack, airspeed, and thrust components being about 54%, 40% and 6%, respectively. The maximum roll rate that can be generated in the lateral control is about 6°/s.
